bacula: Update to version 11.0.6

- Update from version 9.6.7 to 11.0.6
- Update of rootfile
- Ran find-dependencies for the sobump. All libraries are only linked into bacula
- All of the versions from 9.6.7 to 11.0.6 and up to 13.0.3 have no bug fixes relatred to
   the bacula-fd daemon. With bacula-fd running on a separate machine to the bacula-dir and
   bacula-sd daemons, older versions of bacula-fd will work with no bug issues with a newer
   bacula-dir and bacula-sd.
- If we put a very new version of bacula-fd on IPFire then it will not work with older
   versions of bacula-dir and bacula-sd.
- A new feature in the bacula 11 series is that communication between daemons will
   automatically use TLS if OpenSSL is installed on the machines running bacula.
  Therefore having a bacula 11 based bacula-fd on IPFire will automatically, with no user
   configuration required, use TLS for communication to the IPFire bacula-fd from the other
   bacula daemons on other machines.
- This has been shown to automatically work between the bacula-fd daemons on my laptop and
   desktop machines and the bacula-dir/bacula-sd on my server machine.
  Currently communication between mu bacula-dir/bacuila-sd daemons and the IPFire bacula-fd
   daemon communication is still unencrypted.
